Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical grain which can be sufficiently filled when a kernel sorted and lifted by a vertical grain sorter is put into a storage tank and which can be overflowed well. The present invention relates to an overflow device for a sorting machine.

[0002]

2. Description of the Related Art Conventionally, a storage which communicates with a discharge port on an upper side of a vertical sorting machine housing which is internally provided with a lifting rotary cylinder and a sorting mesh tube rod on its outer periphery is provided. In a vertical grain sorter that is constructed by connecting tanks,
No. 42, the grains in the storage tank overflow from an overflow port formed on the outer peripheral wall of the sorter case below the discharge port, and can be discharged through a gutter provided in the sorter case. It was like.

[0003]

However, in such a structure, since the overflow port is erected below the discharge port, the upper surface of the grain introduced into the storage tank rises to the position of the overflow port. When it comes, it immediately flows and overflows, and it is impossible to store each grain sufficiently in the storage tank, and if the size is increased, the cost increases, and a gutter is provided in the sorting machine casing. Therefore, the sorting body in the sorting machine casing is restricted, so that the sorting property cannot be improved, and further, the sorting machine casing has to be enlarged.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised in order to solve such a problem and to make it simple and suitable for implementation. Therefore, there is no space between the separator casing and the storage tank. A valve body which remodels a thin gutter-shaped case, forms an inclined surface having an overflow port on an upper end face of the gutter-shaped case, and presses a weight or an elastic machine toward the overflow port side below the overflow port. Are openably and closably mounted.

[0005]

Therefore, the upper surface of the grain discharged from the discharge port into the storage tank rises as a mountain, but the upper surface of the grain is placed above the inclined overflow port closed by the valve body. The grain can be sufficiently stored in the storage tank until it reaches a certain extent, and when the grain is further thrown in, the skirt side of the upper surface of the mountain that becomes a mountain rises and weighs heavily on the inclined surface Then, while the valve body is automatically opened against the repression, the grains overflow from the overflow port, and are smoothly discharged through the gutter-like case outside the sorting machine casing.

[0006]

FIG. 1 is a sectional view of a main part according to an embodiment of the present invention.
a rotatable sorting net cylinder 2 having a rotatable lifting rotary cylinder 1 having a therein is installed upright, and between the lifting rotary cylinder 1 and the sorting net cylinder 2 from the lower part of the sorting machine casing A. A grain can be supplied, and a sorter casing A
A plurality of discharge blades 8 capable of discharging grains are attached to the discharge port 3 formed on the upper side of the storage tank B, and the storage tank B having the discharge port 9 at the lower part such that the discharge port 3 communicates with the upper part inward. A vertical grain sorter is constructed in the same manner as the conventional type by being connected to the upper side of the sorter case A.

A thin gutter-shaped case C having a discharge port 10 on the lower side is provided between the sorting machine case A and the storage tank B.
And the discharge port 2 is provided on the upper end surface of the gutter-shaped case C.
The lower surface is formed with an inclined surface 4 which is inclined downward and upward in the storage tank B, a rhombic overflow port 5 is formed on the inclined surface 4, and below the overflow port 5,
A valve element 7 pivotally supported by a pivot 6 at the lower part on the upper side of the port 5 and resiliently pressurized toward the overflow port 5 by a weight 6 is mounted to be openable and closable. It is also possible to provide a structure in which a torque spring is interposed in a portion so that the valve body 7 can be elastically pressed toward the overflow port 5 by its elasticity.

Accordingly, while the grains supplied from the lower part are lifted by the lifting rotary cylinder 1 between the sorting net cylinder 2 and the lifting rotary cylinder 1, small grains and dust are removed from the sorting net cylinder 2. When the selected grains are lifted, they are thrown into the storage tank B from the discharge port 3 by the respective discharge blades 8, and the upper surface of the grains is formed into a mountain. Although it will rise, the grains can be sufficiently stored in the storage tank B until the upper surface of the grains reaches a certain extent above the inclined overflow port 5 closed from below by the valve element 7. When the grains are further supplied, the skirt side of the upper surface of the grain which becomes a mountain rises and becomes heavy on the inclined surface 4, whereupon the valve body 7 resists the repression by the weight 6 as shown in FIG. And do not open automatically as shown in phantom lines in FIG. Et al, will be grain from the overflow port 5 overflows, overflowing grain will be discharged by 落流 inside trough-shaped case C.

[0009]

As described above, according to the present invention, the inclined overflow port 5 closed by the valve body 7 is formed in a state where the grains fed from the discharge port 3 into the storage tank B are piled up.
Until the base of the upper surface of the mountain of the mountain of the mountain rises to a certain extent, the kernels can be sufficiently stored in the storage tank B, and the kernels can be sufficiently stored without increasing the size of the storage tank. And overflow 5
Is inclined, so that the valve body 7 can be automatically and satisfactorily opened according to the weight of the grain where the grain is further introduced, and through the gutter-shaped case C while the grain overflows well. The gutter-shaped case C can be mounted between the sorting machine case A and the storage tank B to facilitate the assembly 4, and the inside of the sorting machine case A has good sorting performance. The structure can be made compact, and it has a feature that it can be implemented simply with a simple structure.
